Ok, so I sold my 1440p monitor because I can no longer afford it, I got a 1080 23inch monitor now. However, there is a one inch black border now, and I can't for the life of me figure how to make it all full screen again. Should I reinstall my video card drivers?

The monitor in his sig (Catleap Q270) can be bought for under $350 on eBay, brand new, shipped from Korea. A monitor with similar specs (IPS panel, 1440p res) in the US would probably run you double that, if not more. He probably sold it and downsized to a 23" 1080p TN/TFT panel monitor and pocketed the difference.

I dont know about monitors but my tv is hooked up to my computer via HDMI and i sometimes have to change the underscan - overscan settings in scaling options in the ATI control panel.
AH sorry didn't know you had fixed the problem.
